LADDER BRACE AND RING SUPPORT.

Application filed February 8, 1928. Serial No. 252,848.

This invention relates to ladders and particularly to braces for the ladder and supporting means for the rungs thereof.

The primary object of thisinvention is to provide a brace for a ladder and the rungs thereof that not only cooperate with the openings in the side rails of the ladder to support the rungs, but said braces include penetrating means for securing the braces to the rungs, and said means are adapted to be embedded in the rungs to prevent the turning of the latter in the openings and are so constructed to prevent the splitting of the rungs when the braces are disposed in operative position.

A further object of the invention is to provide a brace with a rung penetrating prong that is adequately and effectively sup-- ported in its true penetrating position.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described i1- lustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a front elevation, of a ladder showing my novel braces associated there with. 7

Figure 2 is a fragmentary sectionalview taken through a portion of one of the side rails of the ladder and showing one of the braces in operative position.

Figure 3 is a perspective view of one of the braces per se. 7 a

Figure 4 is a top plan view thereof.

Referring to the drawings in detail the letter A indicates the side rails of the ladder and the letter B the rungs thereof which have their-ends arranged in openings disposed in the side rails in the usual manner.

The braces which form the subject matter of the present invention are adapted to be arranged with respect to the rungs adjacent each end thereof and each of said braces are formed with right angle portions 1 and 2 with a penetrating prong 3 rising from the portion 1 at the juncture thereof with the portion 2. The penetrating prong is reinforced and supported in its true penetrating position through the instrumentality of a tapered rib 4 which extends longitudinally of the inner side of the portion 1 and merges therein adjacent its free end thereof as clear .60 ly shown in Figure 3 of the drawings. The portion 1 is tapered from its juncture with the portion 2 and is substantially arcuate shape in'cross section so as to follow the curvature of the rungs B. The portion 2 is formed with spaced openings 5 and 6 to receive screws so that the braces can be secured to the rails in the manner as shown in Figure 2. The braces are applied to the ladder after the rungs are positioned in the openings of the side rails, and upon driving the penetrating prongs into the rungs the prongs'will not have a tendency to split the portion of the rung thatis disposed in the openings because of the formation and association of the ribs 4 with the penetrating prongs. It will be apparent that the brace not only adequately and ef fectively supports the rungs but brace the ladder in its entirety. o The portions of the brace are reinforced through the instrumentality of, a pair of cars 7.

It will be understood that the tapered rib will also be embedded in the rungs and s5 cooperate with the prongs and screwsfor retaining the brace in operative position.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be'understood that I may. make changes in the construction and in the combination and arrangement of the several With, a penetrating prong rising centrally from one of said portions at its juncture with the other portion and being adapted to be embedded in the rungs, a tapered rib 5 longitudinally formed with the prong car-. rying portion and merging into the prong for bracing said prong, and said prong care rying portion being substantially arcuate shape in cross section to follow the curvature of the rungs. 10

In testimony whereof I affix my signature. r
